Abstract

A device for controlling the intensity of the light emitted by a lighting element of a lighting apparatus, in particular a flashlight, is embodied as a module which can be arranged in series with the lighting element for the supply of the latter with current. A circuit device for controlling the light-intensity of the lighting element, and a central control device for detecting a detection signal of the detection device as well as for triggering the circuit device are provided. It is made possible with the present invention to dim the intensity of the light emitted by it by variation, in particular in several stages.
